One interesting thing I've learned while programming RUU is that the Rigol only displays 200 of the 256 possible ADC levels at any given time (mapped to the 8 vertical grid divisions) - even though the entire range is available via SCPI. My newest version of RUU (hopefully will post it tomorrow) has a 'Full ADC' switch - to allow seeing the full range.

Here is a clipped sine wave visible on the Rigol display:

And here is the same sine wave displayed in RUU (with 10 vertical divisions) at exactly the same time:

I own a Agilent DSO1024A scope which is made by Rigol. One frustrating thing when viewing a signal with a large dynamic range (amplitude) was that as soon as a peak jutted out of the viewing window (either the top or bottom) then all the measurements that were impacted suddenly became "*****". So a little "headroom" above and below the displayed window in which measurements could still be taken is a good thing IMO.

The Rigol DS2000 will still measure and display the measurements if >top+25% and < bot-25% , and what Marmad is proposing is only in his RUU. data utility program that the Display be extended to show the complete waveform , Great Idea

When part of the trace is outside the extended range the waveform should show clipped as the measurements affected will show ****.

Sure, on many low-end scopes the moment your waveform goes off the screen above or below, then all the measurements were inaccurate. So I'm guessing that's one of the reasons that they've done it.

Here is a 3D-plot of a frame array (RUU does this now ) using the Rigol 8-division screen size - showing a square wave set to the boundaries of the screen. In the plot, each square represents two screen squares (i.e. 7 x 4 = 14 x 8 on the screen). Note the white streaks at the top - that is where the square is touching the screen top (and thus activating the white color in the CLUT):

Here is the same data plotted again - although this time using the full data set mapped to 10 divisions (7 x 5):

Thanks - it's what I've been planning with RUU all along. But since the memory read bug, I had to devise a different scheme to get to my goal. Now the software can save, load, plot, and play 'frame arrays':

Here's a 2D plot of frames of a voltage-increasing sine wave - using a black body color lookup table:

Here's the same frames plotted in 3D using a 2-color gradient on the Y-axis (Edit: Note the frame order is reversed in this plot - increasing away from the front plane):

Something I was wondering about after I have had a DS2202 for testing is:They use the relabled LMH6518, why does Rigol not offer variable gain additional to the fixed vertical scale settings and for this reason the possibility to use the maximum of vertical resolution for any input signal? The LMH6518 has a gain step size of 2dB, which allows additional odd scales beside the standard historical 1 / 2 / 5 scaling.Same functionallity is also available on my over 6 years old TDS5104B.
